Micro-plastics are only about the size of a sesame seed, but they have some scientists asking big questions about what they could mean for the health of our oceans.

Two of those scientists work out of the University of New Brunswick’s Saint John Campus. One is a marine ecologist and oceanologist who studies marine invertebrates. The other is her graduate student, who has found tiny pieces of plastic in clams in the Bay of Fundy.

Ashley Stefureak caught up with them to learn more about their research.
